This example illustrates how to apply basic trigonometric functions to your transformations. All of the functions take inputs in radians.

Source:

In the following sample, input values are in degrees:


X
-30
0
30
45
60
90
120
135
180


Transformation:

In this example, all values are rounded to three decimals for clarity.

First, the above values in degrees must be converted to radians.
